However, they have not found of much utility in clin-

Highlights:
Syncope is a benign disorder in majority of patients.
It is important to rule out cardiac/arrhthymic etiology
as these patients have higher mortality in the long
term.

A detailed history and a meticulous physical exam-
ination constitute the first step towards evaluation of
patients with syncope.

Precise interpretation of the ECG is important to iden-
tify cardiac etiology of syncope.
